Enables you to discover other instances of your app on nearby devices and create a socket connection between the peer apps by using a tap gesture or by browsing. For creating Bluetooth socket connections on Windows 8.1 and later, use Windows.Devices.Bluetooth.Rfcomm instead.

Remarks

You can use proximity to connect computers by using a simple tap gesture. If two computers come within 3 centimeters to 4 centimeters of each other, or are tapped together, the operating system of each computer detects the other computer. You can then connect the two computers to share content or publish and subscribe to messages. Proximity also supports discovery of peer devices via Wi-Fi Direct.

Important

The proximity APIs do not provide authentication, encryption, or message integrity. Do not use proximity to exchange user sensitive information such as passwords, financial data, text messages, email, photographs, or government id numbers.
